Abstract: A refrigerant metering charge board that accurately meters a refrigerant and an associated synthetic compressor oil into a product, preferably a refrigerator, is provided. Metering is accomplished by way of servo motors coupled to ball screws which are in turn connected to hydraulic cylinders. Calibration of the refrigerant, preferably R134a, is maintained using a temperature sensor, a programmable logic controller (PLC) and a density/temperature equation that has been empirically fit to saturation data. The preferred equation is a modified Benedict-Webb-Ruben (MBWR) equation of state. The refrigerant charge amounts are entered into the PLC using either a fixed bar code scanner or a hand-held bar code scanner that reads a bar code on the refrigerator. An operator interface, preferably a touch-screen display is also provided. A charging tool to connect to the product for inserting the refrigerant is located in a chargeable automatic connect/disconnect mechanism (ACDM) which allows for automatic operation on a assembly line.

Abstract: A system for recording terrain profile information is disclosed. The system accurately senses incremental distances traveled by a vehicle along with vehicle inclination, recording both with elapsed time. The incremental distances can subsequently be differentiated with respect to time to obtain acceleration. The acceleration can then be used by the computer to correct the sensed inclination.
